running cmake --build build fails with following on M1 mac

After updating 32b49eb5e7809052a28422cfde2f2745fbb0eb76 to 4e191a4cc872263c60eb473550e2b7d2965690f9 (latest commit on cpu-features main branch) here . I am running into:

I think we need to check whether target is x86 and then only use -march=native, otherwise use -mcpu=native.

Any idea on how to achieve this ?

Hello @Janmajayamall, what version of Clang do you have?

Janmajayamall commented 1 year ago

hey @joserochh! I have Apple clang version 13.1.6 (clang-1316.0.21.2.5)

joserochh commented 1 year ago

Hello @Janmajayamall. Sorry for the late response. Are you looking to benefit from AVX512 by using this library?

The Intel HE Acceleration Library Targets Intel CPUs and we actually recommend using a processor with Intel AVX512DQ support, with best performance on processors supporting Intel AVX512-IFMA52. Looking at the issue you raised here this problem seems to be specific to the M1 chip which unfortunately does not provide support for AVX512.

I am going to proceed by closing this issue as we do not support for M1 CPU.
